1993 chevy 1500 hiccups when you accelerate.
Hi I have a 1993 chevy C1500 2WD 5.7L "350" that almost stalls when you hit the gas from a stop, but it seems to run fine as long as the rpm's dont drop below 1,500 I took it to a machanic and he said it was the pickup coil which I have now changed along with the fuel pump, fuel filter, distributor cap and rotor, and the throttle module on the side of the distributor. There has been no change in the problem although it does seem to come and go on its own one day it will be fine and the next I can hardly drive it. PLEASE HELP.........

I use WD-40 with it running, and hit vacuum connections or palces I suspect it could have a leak. If you hear the engine increase in rpm when you spray an area, that is where you have a leak. The egr valve cleaning is also a good idea.
